What's the difference?
Jeep Australia's first plug-in hybrid, the Grand Cherokee 4xe, has arrived at a time when the company’s sales figures need a decent shot in the arm.
Though it’s seemingly spearheading a large and extra-large SUV hybrid push into the Aussie market, with the likes of a Toyota LandCruiser 300 Series hybrid on its way, the marque’s debut PHEV is only available here in the range-topping Summit Reserve spec, and only as a five-seater.
So, does the 4xe have enough of a jump on any large SUV hybrid rivals – including a rumoured but postponed Ford Everest hybrid – and is it enough to give the brand a much-needed boost?
Read on.
The Sahara used to be the big kahuna of the LandCruiser line-up – but no more.
It now sits third from the top in the LC300 range, under the GR Sport and the Sahara ZX.
However, that doesn't mean it's not full of the good stuff, because if you're looking for luxury and refinement, as well as real off-road ability and towing capability then this loaded LandCruiser pretty much sets the bar... and it sets it very high.
But, in the grand scheme or things, is the Sahara cock o' the walk or a feather duster?
Read on.
A wise man* once said "Being first can sometimes feel like being wrong" and perhaps that's how it is with the 4xe, but at least Jeep Australia is giving the large SUV hybrid realm a good ol' try.

The company's first plug-in hybrid, the Grand Cherokee 4xe, is not perfect by anyone's standards, however, it is a definite move in the right direction.
It's a quiet and refined drive, it retains the brand's renowned 4WD capability, and even its hefty price-tag likely won't dissuade Jeep loyalists from giving it a go.
The LandCruiser 300 in Sahara grade is a very impressive seven-seat 4WD wagon. It's nice to drive, it's refined and – bonus – it well and truly retains that renowned legendary LandCruiser off-road capability.
It's very comfortable and – as with previous-generation Cruisers – has heaps of potential as a top-class touring vehicle, but it has a big price-tag to match, there's no denying that.
While there's plenty to like about the Sahara spec, the GXL offers a nice compromise between price and features as long as you don't mind missing out on leather seats, the cooler box, 14-speaker JBL sound system and a few other bits and pieces.
The Sahara is 4980mm long (with a 2850mm wheelbase), 1980mm wide, and 1950mm high. It has a listed kerb weight of 2630kg.
The Sahara's exterior has that distinctive LandCruiser appearance, but modernised: it's chunky, tough-looking and ready to be kitted out with accessories, whether they be Toyota genuine accessories or aftermarket gear.
Otherwise, there are chrome exterior mirrors and door handles, and dynamic indicators front/rear that add to its overall quietly classy appearance.
The 'Celestite Grey' premium paint on our test vehicle costs $675. Other paint choices include 'Glacier White', 'Ebony', 'Crystal Pearl', 'Silver Pearl', 'Graphite', 'Merlot Red', 'Eclipse Black', 'Saturn Blue' and 'Dusty Bronze'.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV retains the regular model’s level of functionality but adds a reasonably classy touch to everything.
All seats offer adequate comfort, support and room.
There are plenty of storage spaces, cupholders etc, and charging points - two USB-A and two USB-C plus a 12V socket in the front and two USB-A and two USB-C plus a 230V point in the back.
Controls are generally easy enough to locate and operate although some buttons are positioned in awkward places – including drive-mode buttons under the steering wheel – and it sometimes takes a few finger-stabs at the multimedia touchscreen to get to where you want to go in the operating system.
In terms of packability, the rear cargo area has a listed 1067 litres of space, and, with the second row folded and out of the way, that space opens up to 2004 litres.
The LandCruiser is renowned as a great off-road touring vehicle – due to its practicality and functionality – and that reputation is unchanged with the 300 Series.
There's a sense of familiarity in the cabin – it's a functional yet premium space – and it's easy to get comfortable.
The driver is spoilt with a heated and power-adjustable steering wheel and ventilated and heated, power-adjustable seat (with three-position memory). The front passenger also gets a ventilated and heated, power-adjustable seat.
All seats are leather-accented, comfortable and there are soft-touch surfaces throughout the interior.
The Sahara's 12.3-inch colour multimedia touchscreen is a main feature in the cabin and it's easy to use, with wired Apple CarPlay and Android Auto, and there's a wireless charging pad near the shifter. There are USB-A and USB-C charging points, as well.
There's a cool box in the centre console and its lid can be opened from either side, so driver or passenger can access chilled drinks.
There's also a powered sunroof/moonroof, whatever you want to call it.
Beyond those features, there are the usual storage spaces, cupholders, receptacles in the doors for bigger bottles, and other spaces for your bits and pieces.
The second row seats are in a 40/20/40 split-folding configuration, and the third row is a power-folding arrangement that stows away forwards and flat.
The Sahara's cargo space, when all seven seats are in use, is a listed 175 litres (VDA) behind the third row. That grows to 1004 litres when the second and third row are stowed away.
The rear cargo area has a 220V/100W inverter and four tie-down points.
The five-seat Jeep Grand Cherokee Summit Reserve 4xe PHEV has a MSRP of $129,950 (excluding on-road costs).
Standard features include a 10.1-inch multimedia system (with Apple CarPlay and Android Auto), a 10.25-inch digital instrument cluster, 19-speaker audio system, quilted Palermo leather-trimmed seats, air suspension and 21-inch alloy wheels.
It also has a heated steering wheel, 12-way power-adjustable seats and four-way power lumbar adjustment with memory for driver and front passenger, driver and front passenger seat massage function and heated and ventilated seats (driver, front passenger and rear outboard passengers).
A Mode 2 charging cable is also included.
An 'Advanced Technology Group' pack is available as a $5500 option and that includes a head-up display, a 10.25-inch screen for the front passenger, wireless phone charger, and night vision camera.
Exterior paint options include 'Bright White', 'Diamond Black', 'Silver Zynith', 'Velvet Red', 'Baltic Grey', 'Rocky Mountain', 'Midnight Sky' and 'Hydro Blue'.
The seven-seat Sahara has a manufacturer suggested retail price of $133,881 (excluding on-road costs). Surely a chunk of cash by anyone's calculations.
Standard features include a 12.3-inch touchscreen (with sat nav, Apple CarPlay and Android Auto), a wireless phone charger, four-zone climate control, leather-accented trim, a head-up display, a heated steering wheel, heated and ventilated power-adjustable front seats (with three-position driver's seat memory), heated second-row seats (outboard), and power-folding third-row seats.
There is also cooled centre console storage, a 14-speaker JBL premium audio system and a dual-screen rear entertainment system. The list goes on and on...
Suffice to say, you get a lot for your money, but at this price-point, you'd hope so.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has a 2.0-litre four-cylinder turbo-charged petrol engine, two electric motors (one on each axle) and a 17.3kWh battery.
Combined engine and electric outputs for power and torque are 280kW and 637Nm, respectively. The 4xe has it over any of its stablemates equipped with the 3.6-litre Pentastar V6 petrol engine because that yields 210kW and 344Nm.
The 4xe has an eight-speed automatic torque-converter transmission and regenerative braking.
Drive modes include 'Hybrid' (with combined engine and electric motor providing “maximum instant torque and impressive acceleration”, according to Jeep), 'Electric' (“zero emissions”) and 'eSave' (aims to save battery power).
There are a few options available when it comes time to charge the 4xe.
The 4xe vehicle has a Mode 2 charging cable so you can charge it at home in less than 10 hours, according to Jeep.
With a full charge, the 4xe has a claimed driving range, on electric charge alone, of 52km.
Jeep reckons a Mode 3 (wall box) single-phase electric vehicle charger will fully charge the 4xe in less than three hours.
If out and about and looking for a charge, a 4xe driver can use the onboard 'UConnect' system to locate an appropriate public charging station.
The Sahara has the 300 Series' 3.3-litre V6 twin-turbo diesel, producing 227kW at 4000rpm and 700Nm from 1600 to 2600rpm.
It has a 10-speed automatic transmission, high- and low-range 4WD as well as a centre diff lock.
It does not have some very handy 4WD-focussed driver-assist tech that is included in the two higher grades (Sahara ZX and GR Sport) but more about that in the Driving section, further down this page.
As mentioned, the 4xe has a listed electric-only driving range of 52km.
On our official test day, we drove just under 50km on a full electric charge and then the rest of the trip was courtesy of the good ol’ petrol engine.
Jeep's official figure for the combined cycle is just 3.2L/100km, but that's predicated on keeping the hybrid battery charged at all times. On fuel-only we recorded 11.6L/100km.
The 4xe has a 72-litre fuel tank (you need 95RON premium to fill it), so going by that on-test fuel-consumption figure, you could reasonably expect to get a driving range of about 620km out of a full tank.
Add an approximate electric range of about 50km on a full charge to that figure and you have a total estimated driving range of 670km.
Official fuel consumption is 8.9L/100km on the combined cycle.
Our fuel consumption on this test, from pump to pump, was 12.8L/100km, which is okay considering we did a lot of low-range four-wheel driving.
The Sahara has an 80-litre main fuel tank and a 30L sub-tank so, going by those fuel figures above, you could reasonably expect a driving range of about 860km from a fully fuelled start.
We’re all time-poor, right? So, why should I take up your time and rattle on about the 4xe for a thousand words when I can get the essence of it across to you, the reader, in a few sentences? Call me, Mr Thoughtful.
This is generally a big, quiet and refined, easy-steering large SUV, but it feels bulky at times and tends to be quite fussy on irregular surfaces, exhibiting a jittery ride on even brief sections of light corrugations on dirt tracks.
The 4xe’s PHEV set-up is smooth and highly responsive on-road and you can switch between the aforementioned drive modes to suit the circumstance.
Driving range on electric only is listed as 52km. I only recorded a total distance of just under 50km, and it’s a very quiet and smooth drive while relying on electric power.
It regenerates power rather quickly down big hills and via braking, but we’d exhausted all electric charge by the time we’d reached our 4WD test track.
As expected, this Grand Cherokee tackled every off-road challenge without any strife.
The air suspension, set to full off-road height, is a bonus.
Our 4WD test track consists of difficult set-pieces, including one small steep rocky hill that I’ve seen heavily modified vehicles struggle to conquer and, to the Jeep’s credit, it climbed the incline, no sweat.
The 4xe’s efforts were only ever hampered by its 'all-season' Continental CrossContact tyres (275/45R21) which are much better suited to blacktop driving and the fact the 4xe costs upwards of $129,950 and I didn’t want to risk any damage to it.
The 4xe has a listed wading depth of 610mm but our test track was dry so I never had the chance to do any water crossings.
The Grand Cherokee has a solid enough rep as a towing vehicle but, take note, the 4xe is rated to tow 2722kg.
Quiet, comfortable, and easy to spend big days in the driver's seat or as a passenger.
Steering is light and responsive and, with a 11.8m turning circle, this 4WD wagon still feels highly manoeuvrable.
The V6 offers up so much power and torque – and it's all managed so smoothly through the 10-speed auto – that the Cruiser is able to go from standing start to punching along the road at a decent clip, or transition from open-road cruising to safe overtaking without any lag of note.
Ride and handling are well sorted but this is a Cruiser after all so ultimately it tends towards being soft and comfortable, rather than dynamic.
Its suspension – double wishbone, independent at the front and live axle and multi-links at the rear with coils all-around – manages to soak up most imperfections in the road surface.
The 300 Series' brakes – ventilated discs all-around – brought the big Cruiser to a controlled stop during two of my patented 'Watch out for that bloody roo!' set-pieces.
In terms of on-road ride, handling and performance, the 300 Series impresses. But how does it perform off-road?
First things first: the Sahara-spec LandCruiser does miss out on some of the handy 4WD gear that the two higher grades (Sahara ZX and GR Sport) get, namely Toyota's swaybar-disconnect equivalent electronic-'Kinetic Dynamic Suspension System' (included onboard the GR Sport), front and rear differential locks (GR Sport), adaptive variable suspension (Sahara ZX and GR Sport) and a rear torque-sensing limited-slip differential (ZX).
But in the grand scheme of things that shouldn't impede you too much, if at all, unless you're really going all-out to break your Cruiser while 4WDing.
We managed all obstacles at our testing ground without any strife.
A few years back when Toyota announced it would replace the V8 with the V6 there was quite a lot of concern voiced over the change. Let's be frank here: there was a hell of a lot of whinging.
But people needn't have worried because though the V8 was a bloody good engine the V6 produces more power and more torque than it does (up 27kW and 50Nm).
And that power and torque is consistently delivered across a nice spread of revs.
In combination with the 10-speed auto it's a smooth-as pairing. That auto is very clever – smarter than you and me – because it's never hunting through ratios to try and find the sweet spot, it's always bang-on.
High- and low-range gearing are solid in the 300 Series, and the Cruiser has a 50:50 centre diff lock.
And, on top of all that, you also have access to a comprehensive suite of driver assist tech aimed at making your driving life off-road easier and safer.
The traction control system has been really well calibrated – fine tuned, very precise and seamless in its application.
The 300's multi-terrain select system gives you the option of cycling through driving modes such as 'Sand', 'Mud' and 'Rock' to suit the terrain you're on.
In action, those modes adjust vehicle systems, throttle, engine output, etc to give you the best chance possible of getting through every obstacle safely and in a controlled fashion.
Off-road measurements and angles are decent: ground clearance is 235mm, wading depth is 700mm, and approach, ramp-over and departure angles are 32, 21, and 25 degrees, respectively.
So, all in all, in terms of measurements that are suited to hardcore low-range four wheel driving, the LandCruiser 300 Series ticks all the boxes.
And while there's no denying the 300 Series is a big unit, it feels pretty nimble in the bush, even on tight tracks or pinched approaches to hills or creek crossings.
As well as a dialled-in off-road traction control system and all of those driving modes, it has handy tech such as crawl control, which works like a low-speed cruise control.
So, the only flaw in the 300 Series off-road set-up is its tyres, as its standard Bridgestone Dueler all-terrains (265/65 R18) are better suited to dry-track 4WDing in good weather than taking on any difficult stuff.
In terms of towing capacity, the 300 Series can legally tow a 750kg unbraked trailer, and 3500kg braked.
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has the maximum five-star ANCAP safety rating from assessment this year.
Safety gear includes AEB with pedestrian detection, blind-spot monitoring with rear cross-traffic alert, adaptive cruise control, lane-keep assist, driver monitoring, traffic sign recognition, intersection collision assist, and a surround-view parking camera.
The Summit Reserve spec brings with it 'ParkSense' parallel and perpendicular park assist and (low-level autonomous) 'Active Driving Assist'.
It has eight airbags including front, side, and knee (for driver and front passenger), sides (for second-row passengers) and full curtain airbags.
All of the 300 Series line-up, except the GR Sport, have the maximum five-star ANCAP safety rating from testing in January 2022.
Safety gear includes 10 airbags, two ISOFIX anchor points, as well as AEB with pedestrian and daytime cyclist detection, active cruise control (all-speed), 'Lane Departure Alert' (with brake to steer), 'Road Sign Assist' (speed signs only), 'Trailer Sway Control' and more.
Off-road driver-assist tech includes crawl control, downhill assist, hill-start assist, multi-terrain select, multi-terrain monitor with panoramic view, and active traction control (A-TRC).
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has a five-year/100,000km warranty and a lifetime roadside assist service.
Servicing is set at 12-month/12,000km intervals and capped price servicing keeps what you pay for each appointment at $399 for the first five.
The LandCruiser 300 Sahara is covered by a five-year/unlimited kilometre warranty which is par for the course in the mainstream market.
Capped-price servicing applies to the first 10 services at a cost of $375 each (correct at time of writing), which is pretty competitive.
Service intervals are scheduled for every six months or 10,000km, whichever comes first. Which is shorter than the more usual 12 months/15,000km.
That said, owners may extend the engine and driveline warranty to seven years by adhering to service schedules.
